Resumen
In this talk, the potential of controlling the electromagnetic propagation by
periodically-textured surfaces is reviewed. It is shown that backward-wave- and
slow-wave-propagation, superluminal, effective negative refractive index and
highly-confined complex surface waves are obtained with these metallic surfaces.

In this talk, the potential of controlling the electromagnetic propagation by
periodically-textured surfaces is reviewed. It is shown that backward-wave- and
slow-wave-propagation, superluminal, effective negative refractive index and
highly-confined complex surface waves are obtained with these metallic surfaces.
The role of periodicity, complex surface waves and resonant-electric-coupling in
all these phenomena is emphasized and compared against equivalent circuit
models. The explanation of the underlying physics is combined with exemplary
applications focused on the millimetre- and submillimetre-wave band. [--]
